扩张状态观测器用于连续系统辨识

Continuous-time System Identification with the Extended States Observer

使用扩张状态观测器估计连续系统状态和最小二乘法估计系统参数，直接对连续系统进行辨识。仿真结果表明，不管是线性系统还是非线性系统，只要结构对参数是线性的，都能有效地将其参数辨识出来。

The extended states observer is used to estimate the states of continuous-time system, and the system parameters are estimated with the least-squares algorithm. This is a direct approach to continuous-time system identification. If the system structures are linear in the parameters, the simulations show that the method can effectively estimate the system parameters, no matter whether the system is linear or nonlinear. 
